# How to find the length of a line segment?

In this blog post, we will show you how to find the length of a line segment. A line segment is formed by two points and it is also defined as part of a line lying between two distinct end points. So, we can say that a line segment is part of a line that is enclosed in two end points.

## How to find the length of a line segment?

There are a few different ways that you can find the length of a line segment. One way is to use a ruler or a measuring tape. Place the ruler or measuring tape at one end of the line segment, and then stretch it out to the other end. Make sure that the ruler or measuring tape is level, and then read the measurement.

Another way to find the length of a line segment is to use geometry. If you know the coordinates of the two endpoints of the line segment, then you can use the distance formula to find the length.

Formula is, **D = √[(x2–x1)²+(y2–y1)²]**

The most basic formula is the Pythagorean theorem, which states that the length of the line segment is equal to the square root of the sum of the squares of the other two sides. Another common formula is the distance formula, which states that the length of the line segment is equal to the square root of the sum of the squares of the difference between the x-coordinates and the y-coordinates.

The best algorithm for finding the length of a line segment is the Euclidean Algorithm. This is a recursive algorithm, which means that it needs to be defined for two different conditions. First, we need to define the length for line segments where the two end points are known, and second, we need to define the length for line segments where only one of the end points is known.

## How do you find the length of the segment given the two endpoints?

To find the length of the segment given the two endpoints, use the distance formula.

**The distance formula is: **

*d* = *√*[(*x2* – *x1*)² + (*y2* – *y1*)² + (*z2* – *z1*)²]

For example, if the two endpoints are A(3,0,4) and B(0,5,12), then the length of the segment AB is:

How to Use Distance Formula to Find the Length of a Line Segment

To use the distance formula to find the length of a line segment, you will need to know the coordinates of the two endpoints of the line segment. Once you have these coordinates, you can plug them into the distance formula to calculate the distance between the two points.

The distance formula is:

**d = √[(x2–x1)²+(y2–y1)²]**

Where:

**d** is the distance between the two points

x_1 and y_1 are the coordinates of the first point

x_2 and y_2 are the coordinates of the second point

For example, if you wanted to find the length of the line segment that connects the points (2,3) and (6,8), you would plug those coordinates into the distance formula like this:

So the length of the line segment is 6.4 units.
